I actually don't even plan to bring up how she's wronged me. She'll just get defensive and we both know what she did anyway. I'm going to tell her we can't see each other any more and that I wish her luck in the future. So long and thanks for all the fish, as it were. I don't want it to become a "he said, she said" contest or give her any opportunity to argue over minutae. You can't really argue with, "You lied to me, I don't trust you. I forgive you but it's over."
